What is the primary function of coronary arteries?

The primary function of coronary arteries is to supply oxygenated blood to the heart. The heart, like any other organ, requires a constant supply of oxygen and nutrients to function effectively. The coronary arteries branch off from the aorta and wrap around the heart muscle, delivering freshly oxygenated blood directly to the myocardium (the heart muscle itself). This blood supply is crucial for maintaining the heart's ability to pump effectively and meet the body’s demands for blood circulation.

Without adequate blood flow from the coronary arteries, the heart muscle can become ischemic (lacking sufficient blood flow), which may lead to angina (chest pain) or more severe conditions like a heart attack. Thus, the role of coronary arteries in delivering oxygen and nutrients is vital for sustaining heart function and overall health.
